Silent Hill f optimization tweaks and Frame Gen

Lightweight GPU Stability PackThe Lightweight GPU Stability Pack is a small but powerful collection of Engine.ini tweaks designed to rescue Unreal Engine 5 projects and mods from GPU-related instability on 4–8 GB graphics cards. By intelligently capping texture streaming, disabling UE5’s most VRAM-hungry systems, and enabling advanced crash logging, this pack delivers smoother frame rates, fewer crashes, and clearer diagnostics—without touching your game’s core assets or source code.

🔑 Key FeaturesDynamic Texture Streaming Cap — Limits Unreal’s texture pool to a safe percentage of your VRAM so ultra-high-res textures never push you into an out-of-memory crash.

Ray Tracing & Lumen Shutdown — Disables all DirectX 12 ray-tracing and Lumen passes (GI, reflections, hardware rays), forcing UE5 to fall back on lightweight lighting.

Shader Cache Optimization — Activates Unreal’s shader pipeline cache to batch and reuse compiled shaders, reducing hitching and long load stalls.

Optional Frame Generation Toggle — Enables AMD FidelityFX Frame Interpolation for smoother pacing at lower GPU cost.

❓ Why You Need It Unreal Engine 5 defaults to unbounded texture and buffer allocations that can easily exceed 6 GB of VRAM—especially on AMD cards, which are more sensitive to DX12 memory leaks. Even if your rig seems stable under normal play, peak moments (dense foliage, Nanite geometry, large open worlds) will reveal those VRAM overflows as sudden GPU device removals or “GPU Crash Dump Triggered” errors.

This tweak pack pre-emptively reins in Unreal’s appetite before it ever spills over.

📊 VRAM-Budget RecommendationsGPU VRAMRecommended PoolSize

👉 Start with your card’s recommended value, then monitor VRAM usage in MSI Afterburner. If you still experience crashes, reduce by 512 MB until stable—trading off minimal texture pop-in for absolute reliability.

⚙️ InstallationStep 1: Locate your Config folder

C:\Users\YOURNAME\AppData\Local\SHf\Saved\Config\Windows

Step 2: Create Engine.ini if it doesn’t exist

• []If Engine.ini is already there → open it in Notepad.

  []If not → create a new blank text file, rename it to Engine.ini (remove .txt if Windows adds it).

Step 3: Add the tweaks

• []Scroll to the bottom (or leave blank if new).

  []Copy the block for your VRAM size (see below) and paste it.

Step 4: Save and Protect

• []Save the file.

  []Right-click it → Properties → set Read-Only.

  This prevents the game from overwriting your custom settings.
